FLUSHING-TANK FIOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 781,099, dated January 31, 1905.

Application iiled December 26, 1903l Serial No. 186,591.

. To all whom, it may concern.'

Be it known that I, FREDERICK A. SoHos- SoW, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Flushing-Tanks for Water- Closets; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to-make and use the same, referencebeing had tothe accompanying drawings, whichform a part of this specification. Y

My invention relates to an improvement in what is known as low-down tanks for lwater-closets, though it is equally applicable for usein elevated tanks.

In the drawings, Figure l is a longitudinal vertical section through lthe tank and certain of the operating parts. Fig. 2 is a similar sectional view through the tank, showing the operating parts in elevation. l

The object of my invention is to provide means for governing the flush 'and refill which will be simple, sure, and effective in operation, the construction being such that all or practically all the water contained in the tank may be discharged when the flushing-valve is operated, thereby insuring a clean and sanitary tank.

Another object is to provide means whereby the time allowed for the refill after siphoning the closet may be shortened or prolonged to any desired extent to meet the requirements of the closet to which it is connected.

Referring to the letters of reference shown on the drawings, A is the outside or wooden tank. Y

A is the inside metallic lining.

B is a ball-cock controlling the admission of water to the tank', which may be of any approved type.

B/ is the usual iioat governing the valve.

C is the Valve controlling the discharge of water from the tank for iiushing purposes and is provided with the usual overflow-tube C', while mounted on the top ofthe valve and encircling the tube is the cup C2.

D is the valve-seat, provid ed with an eXtenlsion passing through the wall of the tank,

which is threaded on its lower end for engagementwith the usual pipe connections. y

d is a guide-rod rising within the overflowtube from a skeleton frame formed integral with the valve-seat extension. A similar skeleton frame is provided within the overvflow-tube, through which the rod passes and by means of which the valve is guided to its seat.`

- E is a weighted lever pivoted at e and havengaging the nut f', which has a screw-threaded engagement with the rod f2, suspended from the weighted end of the levery E by a linked connection f3.

G is a cone-shaped rod projecting up through the aperture iin the bottom of the can F and preferably supported from an arm cast integral with the body of the ball-cock B.

His a suitable operating-rod designed to raise the flushing-valve from its seat when brought to'bea-r on the weighted end of the lever E.

His an operating-plunger secured to the rod H and sleeved within the casting H2.

I is a stop designed to limit the downward movement of the weighted'ilever E.

The-operation of the invention will now be described. Water being admitted to the tank up to its predetermined level, which is governed by the float controllingthe ball-cock,

the iiushing-v-alve will be held to its seat un -til raised manually by forcing the operatingrod against the weighted endY of the lever E,

.thereby overcoming the balance and raising the valve from its seat.v The Vwater in the tank now passes rapidly out through the Hushpipe until it is discharged, or practically so, at which time the siphoning of the closet breaks. As the water in the can F will only pass out through the bottom as rapidly as permitted by the adjustment of the can with relation to the cone-shapedstem Gr, the weight of the water will hold the flush-valve open until a suitable refill is provided. While the water is being discharged from the can and until the weight of the iiushing-valve overcomes the action of the lever and descends to IOO its seat, the water delivered from the ball-cock serves as a refill for the closet. It will thus be seen that by adjusting the can F with reference to the cone-shaped stem G the water contained in the can serves to hold the flushing-valve from its seat to provide for the refill and may be so adjusted as to prolong or diminish the time allowed for the refill, and thereby regulate the volume of water delivered for that purpose. It will be further understood that the weighted lever, the cup C2, containing water at all times, and the can F are' so adjusted with relation to each other that when the valve C is closed the pressure of the water will hold it closed until manually raised by the operation of the rod H. After raising the flushing-valve is held open until the water in the can F has an opportunity to percolate out through the bottom sulciently to allow the weight of the water in the cup C2 to bring the valve C to its seat. This period of' time, as before explained, is employed to provide the necessary refill after siphoning the closet. While the drawings do not show the valve-seat D flush with the bottom ofthe tank, it may be made flush, so that all of the water therein contained can be discharged.

Having thus described my invention, what I claim isl. In a flushing-tank for water-closets, a

` suitable automatic valve controlling thel admission of water to the tank, a rocking lever, a valve governing the discharge of water from the tank, a receptacle for water mounted on said valve and suspended from one arm of said lever, an overflow-pipe rising within said water-receptacle to a point on the line with the predetermined water-level in the tank and discharging through the releasing-valve, a receptacle for water suspended from the other arm of said lever and provided with a suitable discharge-orifice, and a fixed tapering leak- Valve independent from but governing the discharge of' water from the latter water-receptacle, substantially as described.

2. In a flushing-tank for water-closets, a suitable automatic valve controlling the admission of water to the tank, a' rocking lever, a Valve governing the discharge of water from the tank, a receptacle for water mounted on said valve and suspended from one arm of said lever, a receptacle for water suspended from the other arm of' said lever and provided with a suitable discharge-orifice, a cone-shaped rod projecting into the latter waterreceptacle through said orifice, and means for adjusting the receptacle with reference to the said rod whereby the size ofthe discharge-openin g may be adjusted, substantially as described.

3. In a flushing-tank for water-closets, a suitable automatic valve controlling the admission of` water to the tank, a rocking lever E, a valve governing the discharge of water from the tank suspended from said lever, a water-receptacle mounted on said valve, a water-receptacle F suspended from the other arm of' the rocking lever and provided with a suitable discharge-opening, a cone-shaped rod projecting through said discharge-opening, means for adjusting the altitude of' said receptacle with reference to the cone-shaped rod whereby the size of' the discharge-opening is regulated, and a projecting plunger adapted to engage the rocking lever to raise the liushing-valve from its seat, substantially as described.

4. In a flushing-tank for water-closets, a valve controlling the admission of water to the tank, a rocking lever, a valve governing the discharge of water from the tank connected with said lever, a water-receptacle provided with a discharge-orifice hung from the other arm of' the lever by a screw-threaded rod whereby its altitude may be adjusted, the screw-threaded rod, and a cone-shaped rod projecting up through the discharge-opening of the can to provide for regulating the size ol the opening by adjusting the altitude of the water-receptacle, substantially as described.

In testimony whereof' I sign this specification in the presence of' two witnesses.
